Did you restart your run after that short time?  Did you change the xtc-grps 
option in your .mdp file?

That would be pretty strange.  If they were there, then disappeared, maybe they 
were not written to the .xtc.

If the frame number is not changing, it is done loading the trajectory, or it 
has encountered a problem.  Are there any error messages in the VMD console? 
I'm thinking that you've not written the hexane coordinates to the .xtc file, 
and now VMD is failing because the number of coordinates in the trajectory no 
longer corresponds to the number of atoms in the structure file.
